v2.0.0 roadmap -- paint grass and trees

[radiatoryang]

This is planned for the far future when I have time again, maybe Summer 2020 -- but it wouldn't be very difficult to expand Hedera to simulate grass and trees, and become a complete foliage solution.

Most of the hard part was figuring out the Unity Editor file architecture and core mesh generation. In theory, grass and trees are just another type of ivy: grass is ivy that spreads laterally and points upwards with no branches, and trees are ivy that branch more readily and grow upwards / avoid walls.

But this is pretty low priority for me -- there's already a lot of grass and tree plugins out there, and skilled Hedera users can already use it to paint trees.

that sounds very good!
